    • Data-driven Garment Pattern Estimation from 3D Geometries 

      Goto, Chihiro; Umetani, Nobuyuki (The Eurographics Association, 2021)
      Three-dimensional scanning technology recently becomes widely available to the public. However, it is difficult to simulate clothing deformation from the scanned people because scanned data lacks information required for ...

    • Fast Polygonal Splatting using Directional Kernel Difference 

      Moroto, Yuji; Hachisuka, Toshiya; Umetani, Nobuyuki (The Eurographics Association, 2021)
      Depth-of-field (DoF) filtering is an important image-processing task for producing blurred images similar to those obtained with a large aperture camera lens. DoF filtering applies an image convolution with a spatially ...

    • Neural Motion Compression with Frequency-adaptive Fourier Feature Network 

      Tojo, Kenji; Chen, Yifei; Umetani, Nobuyuki (The Eurographics Association, 2022)
      We present a neural-network-based compression method to alleviate the storage cost of motion capture data. Human motions such as locomotion, often consist of periodic movements. We leverage this periodicity by applying ...

    • Neural Sequence Transformation 

      Mukherjee, Sabyasachi; Mukherjee, Sayan; Hua, Binh-Son; Umetani, Nobuyuki; Meister, Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Monte Carlo integration is a technique for numerically estimating a definite integral by stochastically sampling its integrand. These samples can be averaged to make an improved estimate, and the progressive estimates form ...

    • Pacific Graphics 2022 - CGF 41-7: Frontmatter 

      Umetani, Nobuyuki; Wojtan, Chris; Vouga, Etienne (The Eurographics Association and John Wiley & Sons Ltd., 2022)

    • Recolorable Posterization of Volumetric Radiance Fields Using Visibility-Weighted Palette Extraction 

      Tojo, Kenji; Umetani, Nobuyuki (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Volumetric radiance fields have recently gained significant attention as promising representations of photorealistic scene reconstruction. However, the non-photorealistic rendering of such a representation has barely been ...
